How do I know if I have blown my Holley powervalve?
I have a 750 Vacuum Secondary Holley on a very built 302. The motor backfired a few times through the carb when it was new. I just recently started it after the winter, and noticed
1) Seems to have very strong gas smell,and I see wet butterflies down in carb when motor is shut off
2) Motor is hard to start sometimes when warm - seems to be flooded, if I give it any gas before cranking. Starts only after waiting and gas is not touched.
3) Motor idles very well, no roughness at all
4) Motor pulls great, no issues
Other than the issue of starting when warm, strong gas smell when off, and gas in carb when shut off, no issues.
My question is :
Could I have blow the power valve in the carb during the backfires? What are the symptoms?
thanks for any and all help
